It reminds me of the ignite mechanic in DS, FL etc which was totally RNG. Get ignite = get DPS, get no ignite = get no dps. And it seems like it'll be the same again. If we have to worry again about something which is not up to us that would suck. The current mechanic is cool, you get pyros, you can even gain pyro by yourself using Heating Up. I think it's more of a nerf

What you've said doesn't make any sense.

Ignite between 5.0 and 5.1 has not changed. You will still get the same Ignites you are getting now. You will build them in the same way, you will proc Pyros using Heating Up the same way. The only thing that the Combustion tooltip change suggests is changing is that Combustion will tick for almost 2x as much damage as it currently does (almost, because the Pyro dot is removed, but that was an almost irrelevant part of the damage anyway).

Did I read it correctly that Mages are getting a 50% buff to base mana regen? If so, then the Arcane "nerfs" are not going to have any real effect, I'll be able to continually go to 6-stack on Blast stack before having to terminate the cycle, might even be able to go a couple of blasts over depending on situation.

You know what, I'm not sure if it's nerf. Definitely not for me - this basically means I will be casting Combustion off cooldown, rather than fishing for good ignite AND pyroblast!. Simply means more uptime for combustion.

If your ignite ticks at least more than 2/3 of pyro dot, combustion deals more damage than before 5.1. So, this is not really hard
